Analytical Evaluation of the Impact of Phrase Set on Text Entry Rates
Kent Lyons, S. Mathilda Ave, James Clawson · 2012
Recently the text input community has seen a flurry of research attempting to refine the methods by which input technologies are rigorously evaluated. Specifically, researchers have investigated the validity of the phrases that study participants input when engaged in transcription typing tasks. The phrase set published by MacKenzie and Soukoreff has become the de facto standard for text entry evaluations since its publication. New phrase sets have recently emerged that attempt to address limitations of MacKenzie and Soukoreff’s phrase set. In this paper, we present a preliminary investigation of whether the choice of phrase sets has an impact on potential typing performance by analyzing several different phrase sets using existing typing data from mini-qwerty keyboards.
